HP Systems Insight Manager 7.2 User Guide

4. Physical Servers
This discovery task is for discovery of physical servers (blade servers and standalone servers).
The management processors for these servers must be discovered prior to this discovery task
being run.
5. Virtual Machines
This discovery task is for discovery of virtual machines associated with servers discovered in
the previous category.
NOTE: If discovery tasks are run out of order, errors are likely. Typical errors due to running
discovery tasks in an improper order include:
• Association errors
For example, a server not associated with a management processor or virtual machine not
associated with a virtual machine host.
• Credentials errors
Because discovery of systems can trigger additional discovery of associated systems or
management processors, if the correct credentials are not supplied for the associated systems,
their discoveries are likely to show errors. If you discover these associated systems with a
subsequent discovery task containing the proper credentials, they should then complete
successfully.
NOTE: Citrix Xen VMs discovered in category 5 will always return a discovery error unless the
Citrix Xen Host has been registered through Configure→Virtual Machine→Register Virtual Machine
Host.
If you have a small network, an alternate way of setting up your discovery tasks is to create a
single task with one IP address range and all of the required credentials for the systems in that
range. However, doing this can make it difficult to troubleshoot and diagnose errors if one or more
systems are not configured correctly.
